Alright Omegas are the submissive ones! Although there can be power bottom omegas they will always be the bottom in the relationship. Omegas also tend to be very feminine (even the males). They also tend to be shorter standing at around 4'8"—5'7".

Omegas sents smell sweet and if they are a true omega they will smell very sweet and their sent will be overpowering and irresistible to any alpha especially true alphas. (See chapter 1 or 7 for true alphas/omegas)

Omegas are the ONLY class to have heats and nests!
     A heat is when an omega becomes very very horny and when their boy tells them they need to mate. They start to produce pheromones to attract alphas. The pheromones they produce will cause alphas to get into a rut (see chapter 1).  This heat can last up to a week or as little as 3 days, or until pregnant. Heats only happen every 3 months. They are almost most fertile during this time. During heat male omega will produce slick.
    Slick is a lubricant that males produce through their ass. This is to help the alpha/beta slip in easier and this is also where the pheromone smell comes from. An equivalent to slick for females is when they get wet. Slick is only produced when a male is in heat. But female omega can get wet regardless not heat or not, they will just only produce pheromones when in heat.
   Nests are a safe place for omegas. An omega will make a nest either in a closet (if they prefer tight spaces) or the bed they share with their mate. They will only nest during and after pregnancy. They can however start making a nest before hand if they are planning to get pregnant. A nest will be full of soft things and fluffy things as to comfort the omega. They will also take things that smell like their mate into the nest. Only the mate and pups are allowed into the nest. An omega will get highly protective about their nest and even a mate needs permission to enter the nest. The nest is also where the omega will most likely give birth unless they are having medical issues.

Omegas will give birth like normal unless they are male. They will either have a c-section or they will hive birth through the anus.

Omegas will become VERY aggressive and protective of their mates and pups and nests.

Omegas will be super cuddly around mates and other omegas. Omegas will be attracted to other omegas if pregnant due to the calming sent and understanding of being an omega. Pregnant omegas will give off a different sent.

Omegas also tend to be very motherly in nature though this is not always true.

Omegas have smaller/duller teeth. Although this is true they can still claim/mark an alpha or beta. They do this usually on the chest just below or above the collarbone.

Omegas trill/purr the most often out of all of the classes. They do it when happy or as a sign of love or content.

PRESENTING
1.) Fever in advance (a few days)
2.) may not eat the day before
3.) sent is different (sweet smelling)
4.) jumpy
5.) sensitive to other sents
6.) slow (but smal) weight gain
7.) may produce slick

EXTRA
Omegas will get touch starved, especially when pregnant.

Most omega have a fetish for the following:  being knotted (see chapter 1). Cum in so it looks like they are pregnant. And a daddy kink.

Omegas can get suppressants! Suppressants are a medication that prevents them from having a heat. They are regulated by a doctor. Because each omega is different you must do a blood test to decide the type of suppressant and the dose. You have either take the pill, or a shot every month, or you can get an implant in the arm. This will NOT prevent pregnancy but will greatly reduce the chance.
